Abstract
The utility model provides a semiconductor laser therapeutic device with multi-outputs. The utility model comprises a semiconductor laser pipe, a driving power supply, an output control system, a temperature control system, a power detection system and a casing. The utility model is characterized in that: the utility model can choose to output multi-path of laser simultaneously as required, such as Path one, Path two and Path three. Every path of output is connected with fibre-optical seat and optical fiber, so as to better meet the clinical requirements.
Description
Affiliated technical field:
This utility model is a kind of device of photodynamic therapy treatment tumor on the clinical medicine, after giving the human body photosensitizer administration, to the laser irradiation of tumor locus enforcement specific wavelength, excites photosensitizer to produce active oxygen, kills tumor cell, thereby reaches the purpose of treatment.
Technical background:
At present, the known semiconductor laser treatment apparatus that is used for photodynamic therapy no matter how many general powers of output laser is, all is one tunnel output, can only be connected with an optical fiber.And when clinical practice, need multi-path laser output under a lot of situations.The existing way that solves is to adopt beam splitter.The insertion loss of beam splitter is generally greater than 40%, therefore caused the waste of light, electricity, the more important thing is, when making this semiconductor laser treatment apparatus, need the semiconductor laser tube of high power output, the manufacture difficulty of semiconductor laser treatment apparatus and cost are increased greatly; Simultaneously, because a large amount of losses of laser power make that the multichannel beam splitting is difficult to realize.Therefore, when clinical use, just need repeatedly irradiation treatment, treatment time is very long, and doctor's working strength is increased, and the misery that patient bears is also very big.
Summary of the invention:
The problem that have in order to overcome the device for laser therapy that uses in the existing photodynamic therapy that laser beam splitter is few, single beam power is little, treatment time is long after the beam splitting, this utility model provides a kind of semiconductor laser treatment apparatus, can select to export simultaneously multi-path laser as required, and each road laser output all can directly be connected with optical fiber, thereby avoided the use beam splitter, reduce power attenuation, also can effectively reduce treatment time, satisfied clinical needs better.
The technical solution that this utility model adopted is: use a plurality of semiconductor laser tube in device for laser therapy, and each road semiconductor laser tube has the fiber bench that can link with optical fiber respectively, each semiconductor laser tube can be used a branch power supply circuit, driving power adopts Computer Control Technology, control the output of the driving power of multi-channel semiconductor laser instrument with a CPU, a switching tube is arranged on each branch circuit, when needing this road to export, the switching tube of this branch circuit is opened, this road semiconductor laser tube work, and emission laser; If when not needing this road to export, close or do not open the switching tube of this branch circuit, then the semiconductor laser tube on this road is not worked.Switching tube on each branch power supply circuit is also by computer system control.
The beneficial effects of the utility model are, simple in structure, easy to operate, do not need beam splitter, can effectively reduce power attenuation, reduce treatment time, in the manufacture process of semiconductor laser treatment apparatus, a plurality of lower powered semiconductor laser tube can be used, production technology difficulty and manufacturing cost can be reduced greatly.
